Procomp cylinder head

[outlaw087]

Is ProComp 190cc aluminum cylinder head better head than the 041 heads. I just want to up grade from the 041 to a better head . I just want a good head for reasonable cost +/- $ 600.00 Going on a sbc 355

The stuff I've seen from them is pure junk. Cheap knock off things that sort of look like racing parts. I'd buy a decent set of Darts or something and have something you'll be able to sell if you need to. In the long run you'd be money ahead IMO.

We had to throw a pair of 210cc on so we could race, compared to track 1s they were way off on power.They might be a little better than vortecs.

I bought a set to see what they were like and I put them back on ebay an hour after Fed Ex dropped them off. Very poor castings, valve seats were all different heights, can't cut the spring pockets, couple of the valve guides had too much clearance. This was what I expect from a used set of heads....not new ones.

Thanks for the info.

Really, which heads were they? Who did you buy them from?

190cc runner, 64cc chamber, Pro Comps. I bought them from a guy selling them on ebay a year or so ago. I see now they are selling a 210cc head....not sure if it's any better or if it was designed as a replacement or not. From now on I think I will stick with Brodix or Dart Pro 1's. Much better quality.

My son was rebuilding a 1979 Ford with a 400. He bought a Pro Comp HEI distributor for it and right out of the box....it would never fire on cyl #2 (actually was double firing on #3).

I called a friend of mine who was a Pro Comp dealer and he said he stopped selling their crap because 99% of the stuff he sold kept coming back due to warranty issues. Said it wasn't worth the hassle. Pro Comp doesn't give refunds....all they want to do is send a replacement.

So let me get this straight...

You bought a pair of $450/pr. cylinder heads and you weren't going to do a performance valvejob on them? Hahahaha I wouldn't even try running a set of Brodix or Dart heads without doing a good valvejob on them! As for the loose guide clearance, that isn't acceptable. It does happen from time to time on the Dart Pro 1's that we run too though. Usually, it's not worth the aggrevation of sending a head back so I knock in a new guide or two BEFORE doing the valvejob that the heads require anyways.

As for Pro Comp not giving refunds, isn't that EVERY aftermarket company? Seems to me that most companies have a repair or replace warranty of varying lengths from 30 days to lifetime... Not many companies that have the stones to offer a moneyback lifetime warranty!

Anyhow, thanks for the heads up on the thin spring pockets. Next time a customer brings in a set of those heads, I'll sonic that area just to see how thick it is. I know I've put 200lbs. of seat pressure and 550lbs. of open pressure on a pair of Pro Comp SBC heads and they handled it with no problems. On a 190cc. head, you're probably not going to be running a solid roller that requires any more than 550-600lbs. of open pressure anyway, right?

[parrot69777]

Your right...even dart's and brodix heads need a little touch up... However most decent heads are at least all around the same heights on the seats and not as much as .030-.040 deaper on some. The problems with the depths on the seats wasn't cause by cutting the angles....it was caused by the one who put the seats in in the first place.

Also when I stuck a stock length valve in to check assembled heights....none of them even came close to a stock chevrolet height of 1.75-1.800. They were 1.650-1.700. I like to put a spring locator on aftermarket heads and with these being so tight....my options where either cut the spring pockets some or go to a +100 or +200 valve which I didn't want to do. After making a few phone calls....everyone said NOT to cut anything from the spring pockets.

Guess my point is....I would spend the extra money to buy the good stuff.

ive use some of their parts with no problem i guess it just depins on what you buy from them their stainless rockers and pro i-beam rods ive used and never had a problem and ive ran one of their bilet ready to run distbutors thats a run off of a msd now for 4 year with no problem.

[jsf74]

I'm gonna run their 215's on a sbc for 2012 so I guess well see. Gonna have them checked out first though. Might mill them a little for some more comp too.

[Graff Spee]

The Pro Comp stuff is fine. You should check it out just as you would any other product you buy. I hear all this bad rap on this stuff but in the end the problems are not uncommon to anythig else. The castings that I have seen (not many, 2) small chevy and big ford both looked really nice. There was plenty of meat for port matching and fit perfect. The CNC porting is great for the money! It offers over 60 horse on the dyno. (car craft mag.) The competition can not touch the price! Would I expect to make the top power #'s with them? No, but would I run them before some stock cast iron stuff? You betcha! Its a great product for the price, its just that simple! All the magazines have done testing with them and the results are not bad.

In the long run you spend a dollar to save a dime.

I would disagree.

[50j]

No problem, we'll agree to disagree. I've had enough of that stuff in my hands to know the level of quality, and I wouldn't use it on anything you want to keep. Consider resale value too if they hold up long enough for that. I hope that yours work out for you though.
